Background and study aims
Cystic fibrosis (CF) is an inherited condition which causes the lungs and digestive system to become blocked with mucus. It is caused by a faulty gene, which is responsible for controlling the movement of water and salts in and out of cells. This leads to a buildup of sticky mucus which clogs the lungs and airways causing breathing difficulties and lung infections, and the digestive system which affects the way food travels through and the ability to absorb nutrients from it. Most people with CF experience problems with lung function and usually are treated with a combination of physiotherapy and medications to prevent lung infections and the buildup of mucus that causes damage. Bronchodilator medications are commonly used in the treatment of CF, as they make breathing easier by relaxing the muscles in the lungs and widening the airways. Following bronchodilation, patients are often given normal saline (salt water) through a nebulizer in order to bring up the mucus blocking their lungs. The aim of this study is to investigate the effectiveness and safety of using hypertonic saline (a solution which is more concentrated than in the body) in children with CF.

Who can participate?
Preschool aged children with cystic fibrosis being treated using bronchodilators and physiotherapy.

What does the study involve?
Participants are randomly allocated to one of two groups who receive two treatments for 16 weeks in a different order. The first treatment involves inhaling a mist of 4ml normal saline (salt water), twice a day for 16 weeks. The second treatment involves inhaling a mist of 4ml hypertonic (more concentrated than blood) saline, twice a day for 16 weeks. At the start of the study and then again after 4, 16, 20 and 32 weeks, participants in both groups complete a number of breathing tests (involving breathing into a machine in various ways) in order to measure how well their lungs are working. Throughout the study, any side effects experienced by the children are recorded on a questionnaire.

What are the possible benefits and risks of participating?
There is a possibility that participants may benefit from improved breathing and lung function. There are no notable risks involved with taking part in this study,

InterventionParticipants are randomly allocated to one of two groups who receive two treatments in a random order.

Treatment 1: Participants receive inhalatory administration of 4ml hypertonic saline (HS - 7 % sodium chloride) twice daily for 16 weeks
Treatment 2: Participants receive inhalatory administration of 4ml normal saline (NS - 0.9 % sodium chloride) twice daily for 16 weeks

There is no washout period between the two treatments, and children are followed up after 4, 16, 20 and 32 weeks.
